Pen-type syringes are used to inject infusions of injectable medicines regularly in doses of injections such as insulin injections of diabetics, injection of growth hormones of growing adolescents, patients with asthma, patients with arthritis, allergies, atopic patients, infertile women, Such a pen type syringe is made for the convenience of the user who needs to self-scan frequently by himself as described above.

Insulin is indispensable and must be administered to patients with type 1 diabetes, especially type 1 diabetes. Methods such as inhaled, patch, and oral forms of insulin have been developed and studied, The pen type syringe generally contains an injection medicament which can be injected several times to several tens of times, and a certain amount of the injection medicament can be injected into the human body by pushbutton .

In addition, the pen needle used in combination with the pen type syringe is a one-time product which is used by replacing the needle every time of use due to the risk of infection, and the pen needle is, as shown in Fig. 1 according to ISO 11608-2, A pen needle 11 including a needle hub 11a and a needle tube 11c, a needle-like cap 13, a needle cap 12, And a finishing rod (seal) 15 as one set, and the pen needle unit 10, all of which are once-consumable consumables. In particular, among the above-mentioned components, a cylindrical rod And a needle hub which is inserted through the needle is referred to as a pen needle 11.

The needles 11c fixedly mounted on the center of the pen needle 11 are significantly thinner and sharper than the needles attached to a general medical syringe and are made of a needle And the length of the metal foil is also very short, usually within 12 mm.

In order for the user to self-administer the injection drug, the user first removes the sterilization finish seal (seal) 15 from the needle fastening portion 3a provided at the upper end of the ampule cartridge 3 of the pen type syringe, The fastening portions 11b of the pen needles 11 accommodated in the fastening portions 13 are rotated and connected by a spiral fastening method.

Thereafter, the needle 11c is set on the skin of the human body or the animal by setting the amount of the injected drug, and then injected by the prescribed injecting agent.

After the injection is completed, when the used pen needle 11 is separated from the ampule cartridge 3, the needle-cap 13 is put on the used pen needle 11 again in reverse to the above-mentioned engagement, And inserted into a separate cover or a separate separating mechanism, and rotated counterclockwise or counterclockwise two to four times to separate them in a screw loosening manner.

However, in this conventional method of using the needle 11c, since the needle 11c is exposed to the outside until the pen needle 11 is once removed after the injection, the user or a third person 11c), there is a risk of injury or infection.

In order to solve such a problem, a number of patent documents including Patent Document 1 below disclose various configurations in which the used pen needle can be bent and removed after it is used.

First, a cover (Korean Patent Registration No. 10-1604957) having a one-touch connection and separation pen tip and a one-touch separation discharge function of a pen-type syringe of the following Patent Document 1 is connected to a pen type syringe The pen needle used as a consumable consumable item is rotated by the rotating body inside the lid by using the rotary lever provided on the cover of the pen type syringe after the user uses the pen needle so that the user hands the pen needle A pen with a separation function that can separate the pen needle safely and easily from the body of the pen type syringe without touching it at all, and a discharge function that can discharge the pen needle separated by one touch push button from the inside of the lid to the outside Type syringe, comprising a pen-type syringe and a pen-type syringe, wherein the pen- And a rod-like projection is formed in the rod-shaped protrusion so that the rod-shaped protrusion is staggered with the rod-shaped protrusion of the pen needle. A pushbutton for pushing a circular plate of the lower part of the plunger and a pen for pushing out the penis needle used in the lid, and a push button for transmitting the same rotational force and rotation amount to the rotating body The push button is released from the pen needle by the pushing pressure of the push button, and then the push button is released from the push button due to the elasticity of the spring mounted between the space inside the push button and the inner space of the rotation lever. The push-in through-hole in the entire inner core and the front needle contact plate are opened and then closed again to close Type syringe to prevent dust or air from entering into the lid when the pen type syringe is normally stored with the lid closed, thereby protecting the injected drug receptor of the pen type syringe from external dust or foreign matter. A configuration for a multifunction lid is disclosed.

However, in the case of such an existing invention, there is a problem that the rotating body or the like to which the pen needle is inserted and fixed must be precisely manufactured to match the shape of the needle hub 11a of the pen needle. That is, in the case of the pen needle, the shape, diameter / height, and the like of the needle hub 11a are different according to various factors such as the maker, the length of the needle, and the gauge. However, the present invention corresponds to the shape of the various needle hubs 11a There is a problem that the cover itself must be changed when changing the pen needle to be used.

In addition, since the structure is complicated, not only the manufacturing efficiency is lowered but also the manufacturing cost is increased.
